Application filed August 11, 1813. Serial No. 784,129.

'1 '0 (/71 whom it 711 03/ concern lie it known that I, \ViLLIA B. GRAY,a citizen of the United States, and a resident of Louisville. in thecounty of Jellerson and State of Kentucky, have invented a new anduseful Improvement in Pipe -Supports, of which the following is aspecification.

My invention is an improvement in pipe supports, and has for its objectto provide a support. especially adapted for supporting heating, steampipes and the like, in earthen onduits of the character shown in mycopending application, Serial No. 723,206, filed Sept. 30, 1 912, or inother conduits, wherein a cradle is provided for engaging the conduitand a saddle for engaging the pipe, to gciher with mechanism forconnecting the saddle and the cradle to permit relative longitudinalmovement of the saddle and cradle, and wherein other mechanism isprovided for preventing relative vertical movement of the cradle and thesaddle.

In the drawings :Figure 1 is a perspec tive view of the improvedsupport, Fig. 2 is a top plan view of the saddle detached, and Fig. 3 isa transverse vertical section.

The present embodiment of the invention comprises a cradle 1, having apocket or depression 2, on the upper face of its bottom, provided with aseries of transversely arranged teeth. The side walls 4 and the endwalls 5 of the pocket are approximately perpendicular on their innerfaces, and the cradle is provided at its opposite sides with laterallyextending supporting fingers or lugs (3, the said lugs being near theopposite ends of the cradle.-

The lugs or fingers 6 are adapt-ed to rest in pockets. in supportingribs or ledges in the conduit. and the said fingers are held in thepocket by means of a filling of cement or lead. or other plasticmaterial, capable of hardening.

In order to provide a lock, each of the fingers is grooved on its outerside as indieated at i", the said grooves being adapted to receive theplastic material to form a lock when the said material hardens.

The cradle is also provided at each of its sides with an rip-standingrib 8, and each rib is provided at its upper edge with an inwardlyextending flange 9. the said flange being approximately parallel withthe adjacent face of the cradle.

The saddle 10 is provided at its center with a longitudinally extendingtransversely curved seat 11, for receiving the pipe, the upper face ofthe said seat being shaped to it the insulating covering of the pipe.

Near each end of the seat, a transversely extending ,key block 12 isprovided, the upper face of each of said blocks being curved to fit theperiphery of the pipe, and the said hey blocks are of a depth to extendthrough the insulating covering into contact with the pipe itself.

At each side the cradle is provided with a depending rib 13, and each ofthe ribs is provided with a lateral outwardly extending flange 14:, forengaging beneath the flange 9 ofthe rib 8 of the cradle.

The under face of the saddleproper is provided with a series oftransverse extending teeth 15., the said teeth corresponding in size andarrangement to the teeth of the series 3. The said teeth extend betweenthe ribs 13, and a toothed roller 16 is arranged between the saddle andthe cradle, the teeth of the roller meshing with the teeth 3 of thecradle and with the teeth of the saddle.

The roller is of a length to extend from near one side wall a of thepocket to near the other side wall, and the ribs 13 are spaced apartfrom each other a distance'corresponding to the spacing of the sidewalls 4i of the pocket. The roller is of such length that there will bea clearance between each end of the same and the ribs 13 or the sidewalls 4 of the cradle.

The saddle may be disengaged fi'om the cradle by moving itlongitudinally until the flanges 14c are disengaged from the flanges 9of the cradle. It will be noted from an inspection of Fig. 2 that theflanges 1d are of lesser length than the ribs 13, so that it is notnecessary to move the saddle the full length of the cradle in order todisengage the flanges.

The key blocks 12 are of sufiicient length to prevent rolling of thepipe from ed the said blocks, thus preventing bruising or crushing ofthe insulating covering. At each end of each of the blocks, the seat 12of the saddle is provided with a recess or depression 17, and at theinner end of each of the recesses ordepressions the saddle is slotted asindicated at 18.

Whenthe pipe is in place on the seat of the saddle, the insulatingcovering engages the upper face of the seat, while the p1pe rests uponthe upper faces of the key blocks. The pipe is connected to the saddleby means of bands (not shown), which pass through the slots 18 and bindthe saddle to the pipe.

in the use of the improved support, the cradle is placed in the conduit,the fingers 6 resting in the notches of the supporting ribs, and ascaling medium as for instance, ce-' meat or the like, is placed in thepockets, the pockets preferably having grooves registering with thegrooves 8 of the supporting fingers.

The sealing medium thus enters the grooves and locks the cradle to theconduit. The saddle is connected with the cradle by moving the saddlelongitudinally of the cradle to engage the flanges 14: below the flanges9. The pipe is placed and held to the saddle by the bands.

lVhile the saddle may move longitudinally freely within limits withrespect to the cradle, it cannot move laterally nor upwardly. The cradleis preferably slotted longitudinally of the pocket, and at the centerthereof as indicated at 19, to permit foreign matters to escape from thepocket. The opening extends through the teeth, thus dividing the teeth 3into two series.

The improved saddle is in a single piece, having keepers, the flanges14, for engaging the cradle to prevent upward movement of the saddle.The key blocks 12 are preferably cast integral with the saddle. Thesaddle may be entered from either end of the cradle.

When the saddle is in register as regards length with the cradle, theroller may be at the center of the two series of teeth. After the pipeis laid, the saddle Will move with the pipe to compensate for expansionand contraction, thus preventing any buckling or lateral bending of thesupported pipe.

ll claim 1. In a pipe support comprisin a cradle for ngaging a conduitand a saddle for engaging the pipe to be supported, and the rollerarranged between the saddle and the cradle, the saddle, the cradle andthe roller having interengaging teeth extending transversely of thelength of the pipe to be supported for permitting the saddle to movelongitudinally of the cradle, of ribs on the cradle at each side thereofand extending upwardly alongside the saddle at each side thereof andhaving internally extending flanges, and depending ribs at the sides ofthe saddle depending below the flanges of the cradle and havingoutwardly extending ribs intermediate their ends for engaging the ribsof the cradle.

2. In a pipe support comprising a cradle for engaging a conduit and asaddle for engaging the pipe to be supported, and the roller arrangedbetween the saddle and the cradle, the saddle, the cradle and the rollerhaving interengaging teeth extending trans versely of the length of thepipe to be sup ported for permitting the saddle to move longitudinallyof the cradle, of ribs on the cradle at each side thereof and extendingupwardly alongside the saddle at each side thereof and having internallyextending flanges. and depending ribs at the sides of the saddledepending below the llangcs of the cradle and having outwardly extendingribs for engaging the ribs of the cradle.
